To all whom it may concern:

Be it known that I, NELsoN W. M RLEY, a citizen of the United States,residing in Mentor, Ohio, have invented certain Improvements in HoistingApparatus, of which the following is a speeificz-ition.

My invention relates to that class of h oisting apparatus known astelphers, on which a carriage is mounted upon overhead tracks, thecarriage carrying the motive power, the bucket and the means foroperating the bucket. t

The object of my present invention is to so design apparatus of thistype that the bucket can be turned at any elevation so that it can beused'in unloading vessels which have narrow hatchways, in which thebucket should be turned so as to avoid, as much as. possible, shovelingby hand.

Referring to the accompanying drawings :Figu re 1, is a side view ofsuflicient of a telphe'r to illustrate my invention; Fig. 2, is a planview of Fig. 1; Fig.- 3, is a transverse sectional view on the line 33,Fig. 2; Fig. 4, is a detached side View of one of the carriers; Fig. 5,is a plan view of one of the carriers; and Fig. 6, is'a plan view of aportion of Fig. 2, showing the trucks in a di'll'er ent position. A, Aare the overhead rails supported by any suitable structure; these railsmay be of any length desired according to the distance the telpher hasto travel. Telphers are used extensively for conveying material from awharf or railway to a factory building or from a mine to a point wherethe material is to be used or shipped. Usually the length of the line iscomparatively short.

B is the telpher'having wheels I) mounted upon rails A. There are foursets ofwheels in the present instance, although the number of wheelswill depend considerably upon the length and the weight of the telphercarriage. The carriage has a depending portion B hanging asuilicientdistance below the rails A to contain the operatingcab B andthe hoisting dr 'ims C, C. The telpher'i'sdriven by the motors b,thcrebeing two inthe pres ent instance geared to two of the axles of thewheels I). C is the motor, which drives the hoisting drums C, C.

D is the bucket which may be of anytype, in the present instance thisbucket is of the clam shell type; the b ckets proper d. d being operatedto move apart and to be elevated in respect to the body portion so thatthe bucket can be lowered directly onto the coal or other material anddrawn together, picking up sufficient coal to form a load The bucket inthe present instance is suspended frointwo sets of ropes c, 0, one setof ropes passing around-suitable sheaves on the bucket and on thecarriers E and F re-' spectively to the drums'C and C.

Each carrier'- is made as shown in Figs. 4 and 5, and 1 will nowdescribe the carrier E. This carrier consists of a beam E having at oneend bearings E for the axle of the sheaves e, e and having at the otherend a bearing E for the axle of the sheavese, e

and at the forward end of the carrier is a vertical pin 11 which extendsthrough a truck I having wheels 'L. and at the rear end of the carrieris a pin passing through a truck I having wheels i 'lhusthe carrier issuspended from these two trucks and the rear truck is adapted to railsG, G extending parallel with theside members of the te'lpher carriage,while the forward truck is adapted to rails H, H set at an angle 'asclearly shown in Fig. 2. The purpose of this will be describedhereafter.

Connected to the rear )in i is a head Kto which is adapted a 1'0 It froma piston mounted in a hydraulic cylinder K and also attached to thishead is a rod 7c leading tea con-trolling cylinder K which acts as adash pot so'as to. revent the carrier E moving eyond a pre eterminedpoint.

The carrler F is similar in every respect to the carrier E except thatthe beam F is shorter than the beam E, and the trucks I and I of thecarrier F are adapted to rails in a manner similar to the carrier E; thewheels of the truck I being adapted to rails parallel with the rails G,while the wheelsof the truck I are ada ted to rails II set at an angleand parallel with the rails H.

It will be noticed that the rails are set at such ananglc that uhcn thecarriers are in the positions shown in Fig. 1, the truck I is directlyback' of the truck l and the ropes lead from the carriers so that'thelength of the bucket is longitudinally disposed with respect to thelength of the telpher.

When one carrier is withdrawn and the other moved forward, then theyassume the positions as shown in Figs. 3 and 6, turning the bucket ahalf turn. This turning ot (ill ' the sheaves and ada ited to a bucketthe bucket can be accomplished when the bucket is at hcight.

When the bucket is closed with the load it is again turned andraised out of the hold of tlie vessel and can then be carried to thepoint of discharge. it

will be understood, however, that li'iYlllVOIltion can be used forpurposes other than unloading of vessels, where it is desired to turnthe bucket.
